Abstract:
Carbon nanotubes exist in achiral and chiral forms. The chiral
nanotubes exist as two enantiomers which are each others' mirror image.
By means of symmetry arguments it can be shown that a magnetic field
imparts a linear momentum to the chiral nanotube. Inversely, a moving
chiral nanotube generates a magnetic field. In order to quantify the
first effect, the chiral nanotube is approximated by the quantum
mechanical model of a free electron on a helix. (C) 2004 Elsevier B.V.
